| 摘 要： | 通过斯氏线虫２个品系在不同温度下对毛竹黑叶蜂幼虫侵染力的测定，温度在２５℃时线虫的侵染力量强，可在２—５ｄ内把害虫致死，并且能在死虫体内繁殖。线虫的使用剂量对毛竹黑叶蜂的致死速度及效果有影响，以每毫升１０００条侵染期线虫为最适剂量。室内对毛竹黑叶蜂幼虫致死率达１００％，林间试验两个品系防治效果分别为９６．４２％、９８．３１％。 |

| Abstract: | The infectivity of two strains of Steinernema on Eutomostethus nigrithus larvae was determined under different temperatures.The results indicated that the infectivity of the nematodes was strongest at 25,the injurious insects could be killed within two to five days,they could breed in dead larva bodies,the optimal nematode dosage was 1000 larvae per ml in the infective stage,the indoor lethality for E.nigrithus larvae reached 100%,and the control effect of the two strains was 9642% and 9831%,respectively in the forest experiment. |
